Overdue invoice phone call follow-up: a clear written summary

Prepare the facts before calling

Check the invoice number, current outstanding amount, agreed due date and recent payment records. Read previous replies so you do not ask the customer to repeat information. Decide what the call needs to establish: the right accounts contact, a missing document, a payment date or a specific concern.

Use an established customer contact and an appropriate business time. Keep the invoice and your notes available. If you reach someone who does not handle the invoice, ask for the proper route rather than sharing the full financial history. A short, prepared conversation can identify the next action without a long recital of every reminder you have sent.

Use a short call checklist

Introduce yourself and your business, confirm you are speaking with the relevant person and identify the invoice. State what your records show, then leave room for their explanation. Choose the next question from what they tell you.

• Do they have the current invoice and required reference?
• Has payment been sent, or is approval still pending?
• If sent, what date and reference will help you match it?
• If not sent, what action is needed and who owns it?
• What date was actually confirmed for the next update?

Read back the key action and date before finishing. If the customer raises a dispute, note the specific concern and move to owner review. Do not push for a payment commitment while ignoring the question they have just raised.

A written follow-up email after the call

Send a summary while the details are fresh. Replace the example actions with the ones actually discussed; do not leave a list of possibilities in the email.

Subject: Invoice [number]: summary of our call on [date]

Hi [name],

Thank you for speaking with me about invoice [number]. Our records currently show [amount] outstanding.

My understanding of the next steps is:
- We will [our action] by [date].
- You will [customer action] by [date].
- Payment status: [the precise status discussed].

I'll review the position on [review date]. Please reply if any part of this summary needs correcting.

Regards,
[name / business]

Delete an action if it was not discussed. For payment status, use either a confirmed expected date or “Payment timing is still to be confirmed after approval”, according to the call. Do not fill a missing date with your preferred deadline.

A fictional example: approval is still pending

A web designer calls about invoice W-118 for £800. The accounts contact explains that the project manager needs a handover note before approving it. The designer agrees to send the note that afternoon. Accounts says it will ask for approval on 30 October, but cannot yet confirm payment timing.

The action summary can therefore say:

W-118: call summary, 29 October
I will send the handover note this afternoon.
You will ask the project manager to review it on 30 October.
The payment date is still to be confirmed after approval.
I will check the approval position on 2 November.

It must not say “payment will arrive on 30 October”; that was the approval request date. The review date in this example is the designer's next check, not a customer promise.

Update the record and complete your own actions

Store the call date, contact, relevant summary and next review point with the invoice. Pause or adapt routine reminders so they reflect the conversation. Complete promised documents or answers before asking the customer why the next step has not happened. If they correct your summary, update your note rather than keeping the first version as if it were agreed.

At that check, ask whether the handover note was reviewed. If approval is confirmed, the next question is the payment date. The approval delay guide covers that stage; a payment-date follow-up would be premature while approval remains the unresolved action.
